Over the years, I’ve noticed that certain SQL questions come up repeatedly on the InterSystems Developer Community, especially about using the LIKE predicate in different contexts. Common variations include:

and many more derivatives. So, I decided to write an article that focuses on how LIKE works in InterSystems IRIS SQL, especially when used with variables in Embedded SQL, Dynamic SQL, and Class Queries, while touching on pattern escaping and special character searches.

First of all, I'd like to mention that InterSystems IRIS SQL offers most of the capabilities available in other relational DBMS that implement a later version of the SQL standard. But at the same time, it's important to mention that apart from relational access, in IRIS you can also use other models to get the same data, for example, object or document models.

On this note, let's look at the LIKE predicate and how this tool is used in SQL for pattern matching.

In recent versions of IRIS, a powerful new data loading command has been introduced to SQL: LOAD DATA. This feature has been highly optimized to import data into IRIS extremely fast, allowing hundreds of gigabytes of data to be inserted in seconds instead of hours or days.

This is a very exciting improvement. However, a big problem in the data loading experience still exists. Namely, the time and hassle it takes to:

In the Caché database, when calculating the total count based on the unique identifier of a record, the quantity is over 1.2 million. After removing duplicates based on the unique identifier and then calculating the total count, the quantity is over 400,000. When grouping by the unique identifier, it can be observed that the count for this identifier is not one. However, when performing a conditional query based on the identifier, only one record can be retrieved. Why is this the case?

Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.

Dynamic Objects

Dynamic Objects are very similar to the standard ObjectScript object model you get when you create a new instance of a class object, but with some key differences:

Is there a way to Remove specific all Addresses from a Provider.Individual.Address before reinserting the Addresses from an HL7 message in Provider Directory?

Most fields we can call %clearFields() however since Addresses come from multiple locations we need to isolate and treat Addresses from this HL7 source as a snapshot.

Thanks

Scott

⏯️ MyVitals: Connecting Wearable Health Data to EHRs with InterSystems

MyVitals is a Personal Health Device Hub that bridges the gap between wearable health devices and clinical workflows. In this demo, we show how healthcare organizations can enroll patients, collect real-time data from personal devices via mobile apps, and seamlessly integrate that information into EHR systems using FHIR, HL7, and InterSystems technology. Built on IRIS for Health and FHIR repositories, MyVitals turns disconnected wearable data into actionable clinical insights—securely, efficiently, and at scale.

Question
· Aug 9
Manifest or Class?

I have the unfortunate job of installing IRIS and Healthshare (real Healthshare not Healthconnect) on 16 difference instances (tst, stg, prd with mirrors etc). the Dev was set up manually (mostly by me).

So I decided to create a class that installed the db's, namespaces, mappings and HSREGISTRY options , i then decided an installer manifest was a better idea, I keep changing my mind on which!. I understanding manifest is "typically" for dockers to create the environment but have seen ISC use them for creating new setups aswell (outside docker)

The operations manager in our company was using structured logging in IRIS to tail information to an on-prem monitoring tool and started to get concerned with the ever-growing size of the output file. He just leaned across the aisle here and informed me that the output file has no mechanism for rolling this file over at a certain point for archival or disposal. Sure enough, I can't find any documentation to refute this.

Hi everyone,

I am trying to create a treeMapChart in IRIS BI that will then be displayed on my DeepSeeWeb dashboard. In the IRIS BI User Portal, this is an example of what my treeMapChart looks like:

I know there is a huge amount of rectangles in this graphic - I care most about the common components (the largest boxes) but I still want all of the boxes to show. However, it projects to my DeepSeeWeb dashboard as the following:

For example, you start debugging the AAA function, which calls the BBB function, then goes to the CCC^ABC function in a different routine and ends up while executing XXX^XYZ. No other routines or functions are visited in this example. What I would like is to get the record of AAA -> BBB -> CCC^ABC -> XXX^XYZ. No marking each function with recording code should be involved: too time consuming, too many functions in real code.

UPD: Iris has built in %SYS.Trace for this purpose but this class is apparently absent in Cache 2017. Did not find any substitutes yet.

I have a personal copy of Cache which I use to help me with certain things. The instance resides on my Windows desktop. The apps I use a web enabled. It would be great if I could access my apps via web browser from my laptop without having to keep a copy of Cache on my laptop. It would make it difficult to keep the databases synced. So, if I restart my Cache instance, then I can use get to my apps by entering the url: http://ipadd:57772/csp/user/myapp.cls.

Been testing out the Production Validator toolkit, just to see what we can/not do with it. Seems really interesting and there seem to be some use cases for it that can really streamline some upgrades (or at least parts of upgrades) but I was running into so many hurdles with the documentation. I am curious if anyone else has used it.

When I open a class in VS Code and I want to save it I'm getting the following error : Non-JSON response to /api/atelier/v7/DEV/doc/API.Mollie.Execute.cls?ignoreConflict=0 request. Is the web server suppressing detailed errors?

Also I always get a popup when I open VS Code "The extension wants to sign in using InterSystems Server Credentials."

Kubernetes horizontal pod auto-scaling (HPA) is the key to handle the unpredictable compute workload in healthcare systems.

This great article sparked some recent private discussion, and I'd like to share some of my own thoughts from it.

The motivating concern boils down to: Why do we need coding rules or conventions at all? What happened to the wonderful era of the Renaissance artist-programmer forging their own path, prior to being supplanted by the craftsman and now (even worse) by AI?
